|
18 |
cc: Checksum (The checksum field consists of a "*" and two hex digits representing the exclusive OR of all characters between, but not including,
the "$" and "*" characters.) |

Measurement from (location)
Three characters are used.
|
• |
The first character identifies the trawl(s) These are listed from port towards starboard, and starts from "a". |
|
• |
The next characters identify the physical location of the sensor on the trawl(s). This is expressed with one or two characters. |
On a dual trawl, the location on the clump is defined as a2 while the starboard door is b2. On a triple trawl, the clumps are a2 and b2 while the starboard door is c2.
